I have probably been growing herbs for three or four years now. Seems to me, there's honestly hardly any science to it. Sometimes there is, but for the most part, they're pretty easy to grow. I do admit, for some reason there are ants on my German thyme, sometimes little cooties like to gnaw on my Basil leaves, but really. Think about it. Take mint for instance. It's easy to grow and hard to kill. Perfect combination for such a beneficial plant! In addition, there are countless varieties. Here are a few that I grow.
But really, it doesn't matter if you are a city slicker and only have a back porch to work with, or if you're a hayseed and have the back fifty to work with, you can grow herbs anywhere. And they're so much fun!! Medicinally, culinary, or teaching your little sibling how to differentiate bee balm from lemon balm. :)
If you have them, enjoy them. Use them. Savor their aromas. Thank God for these wonderful blessings!!
